Soil stabilizer

Abstract

The invention discloses soil stabilizer, which consists of industrial waste and chemical reagent, wherein the industrial waste consists of ground steel slag, coal gangue powder after being spontaneously-combusted, grain slag or furnace slag, the chemical reagent consists of calcium oxide, powder grinding aid and sodium sulfate, wherein the mass ratio of the industrial waste and the chemical reagent is 7: 3, and the fineness of the stabilizer powder is brinell specific surface area 500 to 900 m<2>/kg. The soil stabilizer has beneficial effects that mixture of the industrial waste is adopted as raw materials, so that the environmental pollution caused by the industrial waste can be solved; the original chemical activity of the mixture is used for rapidly condensing and solidifying the soil and sand, and no other surface active agent and alkaline excitant is needed, so that the cost is remarkably reduced, simultaneously the construction speed is fast, and the delivery period can be shortened; and the soil stabilizer is widely applied to the dam crest solidification and slope protection of foundation layers of road engineering and hydraulic engineering and is free from being restricted by any environment.

Description

technical field [0001] The invention belongs to the technical field of engineering materials, and in particular relates to a soil curing agent. Background technique [0002] At present, there are three main types of roads in most areas of our country, one is mountain roads dominated by soil, the other is gravel roads formed by mixing sand and gravel on mountain roads dominated by soil, and the third is black asphalt concrete roads; Dirt roads and gravel roads have a lot of dust on sunny days, and they can't see clearly, which poses great safety hazards to pedestrians and vehicles. In rainy and snowy weather, soil and sand are used as road filling base materials, which may cause dehydration. Defects such as easy to slide and collapse, difficult to compact, and poor water stability can easily cause mudslides. Due to mudslides, roads are blocked and normal production operations and traffic cannot be carried out. It is inconvenient to come, and it is not easy for rescue vehicle...

[0002] At present, there are three main types of roads in most areas of our country, one is mountain roads dominated by soil, the other is gravel roads formed by mixing sand and gravel on mountain roads dominated by soil, and the third is black asphalt concrete roads; Dirt roads and gravel roads have a lot of dust on sunny days, and they can't see clearly, which poses great safety hazards to pedestrians and vehicles. In rainy and snowy weather, soil and sand are used as road filling base materials, which may cause dehydration. Defects such as easy to slide and collapse, difficult to compact, and poor water stability can easily cause mudslides. Due to mudslides, roads are blocked and normal production operations and traffic cannot be carried out. It is inconvenient to come, and it is not easy for rescue vehicles to reach the work area, so expensive expenses are needed for road repairs and daily maintenance, and due to unsmooth road traffic, many products cannot be transported, which will definitely cause huge economic losses. Once someone dies, The price is even more painful; asphalt concrete roads in cities and roads paved with soil curing agents obviously solve this problem of dirt roads and gravel roads to the greatest extent, but when laying asphalt concrete pavements, according to the specifications It is also necessary to clean up the original sand and gravel to ensure the overall stability of the base, which will generate a large amount of road construction waste; and most of the current soil curing agents use cement clinker as raw material, add some cement auxiliary materials and chemical reagents to mix After being ground by a cement mill before use, a large amount of coal resources will be consumed in cement production, and a large amount of carbon dioxide greenhouse gas will be released. Over time, it will cause a shortage of resources and aggravate the greenhouse effect. The current soil curing agent is also useful. Soil stabilizer made of slag as raw material, but all need some alkaline activator and surfactant to improve chemical activity
